    public Integer colCount { get; set; }
    
    public List<List<String>> getResults()
    {
        List<List<String>> parsedCSV = new List<List<String>>();
        rowCount = 0;
        colCount = 0;
        if (contentFile != null)
        {
            String fileString = contentFile.toString();
            parsedCSV = parseCSV(fileString, False);
            rowCount = parsedCSV.size();
            for (List<String> row : parsedCSV)
            {
            name=row[2];
            system.debug('??????????????????'+name);
            
            for(string name:row)
           
                if (row.size() > colCount)
                {
               
                    colCount = row.size();
                }
            }
            
        }
        return parsedCSV;
    }
    
    /*public Pagereference CreatePDF()

     }*/
    
    public static List<List<String>> parseCSV(String contents,Boolean skipHeaders)
     {
     
        List<List<String>> allFields = new List<List<String>>();
        contents = contents.replaceAll(',"""',',"DBLQT').replaceall('""",','DBLQT",');
        contents = contents.replaceAll('""','DBLQT');
        List<String> lines = new List<String>();
        try
        {
          lines = contents.split('\r'); // using carriage return accomodates windows, unix, and mac files
        }
        catch (System.ListException e)

            System.debug('Limits exceeded?' + e.getMessage());
        }
        Integer num = 0;
        for(String line: lines)
        {
           if (line.replaceAll(',','').trim().length() == 0) break;
            List<String> fields = line.split(',');  
            List<String> cleanFields = new List<String>();
            String compositeField;
            Boolean makeCompositeField = false;
            for(String field: fields)
            {
                if (field.startsWith('"') && field.endsWith('"'))
                {
                    cleanFields.add(field.replaceAll('DBLQT','"'));
                }
                else if (field.startsWith('"'))
                {
                    makeCompositeField = true;
                    compositeField = field;
                }
                else if (field.endsWith('"'))
                {
                    compositeField += ',' + field;
                    cleanFields.add(compositeField.replaceAll('DBLQT','"'));
